Material Mechanical Properties Necessary for the Structural Intervention of Concrete Structures
Structural intervention involves the restoration and/or upgrading of the mechanical performances of structures. In addition to concrete and steel, which are typical materials for concrete structures, various fiber-reinforced polymers (FRPs), cementitious materials with fibers, polymers, and…

Meso-scale modeling of chloride diffusion in concrete with consideration of effects of time and temperature
A meso-scale truss network model was developed to predict chloride diffusion in concrete. The model regards concrete as a three-phase composite of mortar matrix, come aggregates, and the interfacial transition zone (ITZ) between the mortar matrix and the aggregates. The diffusion coefficient of…

Study on Shear Behavior of Concrete-polymer Cement Mortar at Elevated Temperature
In this experimental and analytical work, interfacial shear strengths were evaluated at material and member level. Bi-surface shear strength was performed at material level and three-point bending test was conducted at member level. Beams were strengthened by adding steel reinforcement at soffit…

Bond-Slip Models for FPR-Concrete Interfaces Subjected to Moisture Conditions
Environmental related durability issues have been of great concerns in the structures strengthened with the fiber reinforced polymers (FRPs). In marine environment, moisture is one of the dominant factors that adversely affect the material properties and the bond interfaces. Several short-term and…

Natural fiber-reinforced light-weight cement blocks prepared from waste for sustainable development
Low density of the light-weight cement blocks offers an advantage in terms of dead load reduction, which is advantageous in structural design-reduction of size and numbers of load-carrying structural components is possible. Production of cement blocks, however, generally requires Ordinary Portland…

Generic 3D conceptual stress-strain model for concrete confined with fiber reinforcement polymers
This study proposes a generic 3D conceptual stress-strain model for concrete confined with fiber reinforced polymers (FRPs), integrating both synthetic and natural fiber materials. The proposed model addresses limitations of existing confinement models by providing a unified framework that…

Atomic-Level Insights into Epoxy-Modified Nanofiller Adsorption and Wetting on Calcium Silicate Hydrates: Principles for Optimizing Interfacial Properties
Cementitious composites are ubiquitous in infrastructure, but their durability is often limited by interfacial weaknesses, particularly when bonded to epoxy polymers. These organic–inorganic interfaces are critical in applications such as fiber-reinforced polymer repair, strengthening, and additive…

The influence of testing conditions on damage zone of concrete in Uniaxial Compression: Insights from Stereo-DIC and computational modeling
With recent advances in non-contact optical measurement techniques, studying the response of concrete materials under specific mechanical loading conditions is evolving toward obtaining full deformation fields and mesoscopic mechanisms. Such data fields can be used to validate and improve theories…
